1:18 scale. After the shock decision by Holden in late 2016 to remove the “official factory racing team” title from the Walkinshaw-run Holden Racing Team for 2017, the Walkinshaw outfit had some big changes to plan for. This model will be produced in die-cast presented in our clear acrylic display case in an exclusive limited edition with a numbered Certificate of Authenticity. It’s one that the Walkinshaw army and JC fans shouldn’t miss.
